Design with Real-Time Supply Chain Visibility
Flux takes a different approach. Instead of treating pricing and availability as a post-design concern, Flux keeps live supply data connected to your project as you work. Your project becomes a living document that stays aligned with the supply chain, surfacing constraints early—when decisions are still flexible and changes are cheap.
When you browse and select parts in the part library, Flux shows pricing and availability so you can spot sourcing constraints early. The Part Library panel is collapsed by default—expand it to see full pricing and availability details. You can also filter by stock status using the cart icon to show only available components.

To expand the part library panel, hover your mouse at the leftmost edge and drag it to the left.
Ask Flux AI to find parts that are in stock—it searches real-time supply chain data and understands your full project context. Instead of manually checking distributor websites, you get parts from the library that match your requirements and constraints.
Example prompt:
"I need a 16-bit ADC with at least 1 MSPS sampling rate for a battery monitoring application. Find what’s available within 2 weeks?"

Ask Flux AI to find a replacement that's in stock. It understands your full project context, including what the part connects to, how you're using it, and your design requirements and constraints, and suggests parts with similar packages and specifications.
It prioritizes availability over minor price differences and recommends parts already in the library, so you don't have to build them from scratch. Once you select a replacement, Flux AI can automatically drop it onto the canvas and wire it up for you.
Example prompt:
"Can you find me a cheaper replacement for U2?"

To check availability for a part, click on it in your design to open the inspector panel on the right. Scroll to the bottom, and you'll see real-time stock levels across multiple distributors—Arrow, Mouser, DigiKey, LCSC, Verical, and TME. This gives you a clear picture of whether a part is widely available or at risk of supply chain issues. If the part isn't in Flux's library, the system can search the broader internet to find availability data.
Note: You'll need a manufacturer part number (MPN) defined in the MPN property for generic parts.

Click on a part to pull up real-time availability at the bottom of the inspector.
Supply chain constraints don't go away once you've finalized your design—they just become more expensive to fix. The earlier you catch them, the more options you have.
Start treating sourcing as a design constraint, not a procurement problem. Check availability when you select parts. Let Flux AI flag risky components before you commit to a layout. And when something goes out of stock, find alternatives while you still have room to adjust.
The tools are already in your workflow. Use them before the BOM forces your hand.

With the latest release of Copilot it isn’t just smarter—it’s hands-on, placing components and applying bulk changes to your project instantly. But to get the most out of it, knowing how to craft the right prompt is key.

Imagine an AI teammate that doesn’t just chat about your PCB ideas, but actively transforms them into schematics—placing parts, connecting circuits, and optimizing your design at your command, all through natural language. That’s exactly what the newly overhauled Flux Copilot does.

Whether you're migrating from popular EDA applications or starting fresh, mastering high speed PCB design has never been more intuitive. Flux enables teams to design, simulate, and route with real-time AI assistance, so you can spin your next high-speed board with total confidence.

This Spring 2026 updates make hardware design faster end-to-end with a more capable, self-correcting AI agent, improved AI auto-layout that needs less cleanup, sourcing-aware design with real-time pricing and availability, and templates to start from.

Today we’re excited to share that Flux has raised $37M in new funding led by 8VC, with participation from Bain Capital Ventures, Liquid 2 Ventures, and Outsiders Fund, alongside Lenny Rachitsky, John Lilly, and Tom Preston-Werner and many other world-class operators.

Flux's AI agent is now up to 10x faster and self-corrects in real time, delivering cleaner schematics with less waiting and fewer wasted credits.

This blog compares AI capabilities across Flux.ai, Altium, KiCad, and EasyEDA to answer engineers’ highest-intent questions about modern PCB design. It explains why Flux.ai currently delivers the strongest end-to-end AI workflow in the ECAD space.
